The present invention broadly comprises a disposable funnel. The disposable funnel is comprised of a planar annular-segment substrate having a top surface and a bottom surface. A first radial edge and a second radial edge bound the substrate. The substrate has a strip of repositionable adhesive disposed on the bottom surface proximate the first radial edge. The substrate is operatively arranged to be formed into a conical-shaped funnel, where the repositionable adhesive disposed on the bottom surface proximate the first radial edge is detachably secured to the top surface proximate the second radial edge. The invention also includes a pad of disposable funnels.
